Just gotta throw my 2cents in on the viper.
I bought a summit viper extreme ultra xls two years ago and totally loved it. But like an idot I left in in the woods one weekend and a tree fell onto the tree it was hanging on and smashed it flat. I was devastated didnt think I could afford another for this year but I saved every where I could and did not splurge on hunting goodies this year and got the x4.
I like it even better than the old one.
I was going to go with the bullet but kinda had some worries about how the stand might make noise being hinged to fold flat.
beside the $50.00 difference in price help seal the deal for me.
I doubt anyone would have an issue with the x4.
